Okay I bought a 95 Civic sedan 4door Lx or dx I’m not really forsure but I bought a D15b7 engine an Manual transmission swap to put in it and I am using a p06-A02 ecu which is non vtec but I’m using a d16z6 wiring harness which with the z6 & b7 it’s plug & play well the swap didn’t have a Throttle body on the intake so I had a d16z6 that spun a bearing an was just sitting so I took the throttle body off an put it on my first swap/project well the only lights showing was fuel light battery an emergency brake so I gotta fuel filter an charged battery lights went away I plugged everything up from the diagrams An even my homie pulled his car beside mine cause we have same engine but he has a hatch but we matched the wiring harness Colors to make sure it was right an it was so when I cranked at first it was idling like **** up an down up an down but then next day did it again an ehh didn’t sound as shitty as the first time so I got me some Throttle body an carb cleaner spray an sprayed on the Throttle An manifold wiped it down as best as possible An waited till next day it sounded pretty decent but still idling weird after 20 seconds of normal idling so I took the Throttle off An yes there was build up I made it spot less looking almost new An I took the IACV off An cleaned it very good there was dirt in the screen An after I put it on fixed the Throttle cable it sounded 10x better but not good enough let alone I don’t have A FitV or plate closing **** off I don’t think so that could be a reasonable possibility but since I’m getting the TB felpro gasket tomorrow it’ll hopefully help out to with the idle but since the ecu is non vtec An the Throttle body I’m using is vtec an it’s using basically it’s own wire harness the map sensor for the b7 goes on fire wall An the z6 is on the Throttle well I have a map sensor that I got from a junk yard same car an engine as mine with fuel filter but never used it cause it was old *** filter so I kept the map sensor an I was wondering if I just unplug the z6 harness map sensor off the z6 Throttle body map sensor An put it on this one that I got off the fire wall where a b7 is originally supposed to go will it be any different An I’m getting a tb gasket today to help out as well but do I still need to get the FitV ? And when I was gonna drive it I put it in reverse An when pressing gas it just revs up don’t move I am getting Transmission fluid as well An gonna check that today cause I’ve read that can make it where it don’t go in reverse but I can go into every gear just fine or is there like a certain sequence then shift in reverse? I’m not forsure lmk
